Magnet lab researcher exploring science behind commercial applications of liquid helium
In a letter published in a recent issue of Nature Physics, Van Sciver wrote that when superfluid helium flows toward and then around a relatively large object, say the size of a small stone, it has a tendency to create whirlpools not just in the back, as would be expected, but also in the front.   view more (2005-12-12)

HRCT Reveals Asthmatic Risk Long After Cat Allergen Exposure
For the first time, researchers have shown that cat allergens can impair lung function in people with asthma for up to 22 hours after exposure. The study was presented today at the annual meeting of the Radiological Society of North America (RSNA).   view more (2005-11-30)

Innovative nanomaterials processing points to advances in semiconductor optoelectronics
The study of semiconductor nanoparticles embedded in a matrix is currently a very active research area. These small particles have physicochemical properties quite different from those in the bulk material.   view more (2005-11-15)

UC Santa Barbara researchers light up 'dark' spins in diamond
Researchers at UC Santa Barbara have potentially opened up a new avenue toward room temperature quantum information processing. By demonstrating the ability to image and control single isolated electron spins in diamond, they unexpectedly discovered a new channel for transferring information to... view more (2005-10-27)

Proofreading and error-correction in nanomaterials inspired by nature

Physicists Entangle Photon and Atom in Atomic Cloud
uantum communication networks show great promise in becoming a highly secure communications system. By carrying information with photons or atoms, which are entangled so that the behavior of one affects the other, the network can easily detect any eavesdropper who tries to tap the system.   view more (2005-07-27)

Soil fertility in the tropics can be influenced by landscape and precipitation, study finds
A new study conducted in the Hawaiian Islands has revealed that landscape and erosion play crucial roles in determining soil fertility in tropical ecosystems.   view more (2005-07-20)

A new particle discovered by BaBar experiment
Its name is Y(4260) and it is not a new humanoid of Stars Wars, but a particle identified for the first time by BaBar experiment: an international collaboration-formed by the large participation of the Italian physicists of the National Institute for Nuclear Physics (Infn)-that has its seat in... view more (2005-07-07)

The Shifty Nature of Grains
In separate papers appearing in this week's Nature, researchers announce findings regarding the little-understood world of granular materials, systems of particles that can dictate the flow of avalanches, the quality of concrete and even the mixing of pharmaceuticals.   view more (2005-06-24)
